"Did you have a good meal? "he asked ."yes,thank you ."I answer."I can't pay the bill . I haven't got my bag."The inn-keeper smiled and immediately went out .In a few minutes he returned with may bag and gave it to me."I'm very sorry." he said ."My dog look it into the garden . He often does this".
